  1. The Average Cost in the table above represents Basic Pay/ Employer National Insurance/ Pension only and does not include other costs such as those associated with recruitment, training, clothing, stock consumption, infrastructure, or medical/dental care.
  2. The Basic Pay includes X-Factor payments.
  3. The Employer National Insurance would be 0% for some of the populations (I.e., general population under the age of 21 and apprentices under the age of 25).
  4. The Average Cost was determined using the Joint Personnel Administration (JPA) data. The mean average across the Infantry soldiers was calculated using the mean average of every Infantry soldier’s pay records to create a monthly estimate, which was then multiplied by 12 to obtain a yearly estimate.
  5. The Financial Year for statistical purposes runs from 1 April to 31 March.
